Summary of Changes
Hello @gaby, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
I've updated the documentation for the Favicon middleware to provide clearer information regarding its behavior and configuration. The primary goal is to ensure users understand which HTTP methods are handled and the correct type for the FileSystem option.
Highlights
- Favicon Middleware Behavior: I've added a note clarifying that the Favicon middleware only handles GET, HEAD, and OPTIONS requests for the configured URL, returning a 405 Method Not Allowed for other methods.
- FileSystem Type Update: I've updated the documentation to reflect the correct type for the FileSystem configuration option, changing it from http.FileSystem to fs.FS and providing examples like os.DirFS or embed.FS.

9-10: Clarify the exact behaviour of the allowed methods
The sentence correctly states the accepted methods, but readers may still wonder what the middleware does for each of them. A tiny add-on keeps the docs self-contained:-It only handles `GET`, `HEAD`, and `OPTIONS` requests to the configured URL. Other methods receive a `405 Method Not Allowed` response. +It only handles `GET`, `HEAD`, and `OPTIONS` requests to the configured URL. +• `GET` / `HEAD` – the icon is returned (200). +• `OPTIONS` – an empty `204 No Content` with an `Allow: GET, HEAD, OPTIONS` header. +All other methods receive a `405 Method Not Allowed` response.
53-53: Sync the table change with the “Default Config” snippet
The newFileSystem fs.FSrow is great, but the “Default Config” block further below (Lines 58-65) still shows onlyNext, File, URL, CacheControl. That mismatch can confuse readers scanning for a full example.Either append the missing zero-value fields there or add a short note that omitted fields take their Go zero-value (
nil,"", etc.).
